Title: Improvements in or relating to organopolysilane resins
IPC: C08G77/60
Filed: 1950-04-26
Abstract: In making an organopolysilane resin, in which the silicon atoms are interconnected and the remaining valencies are satisfied by phenyl and methyl radicals the average number of which are from 1.2 to 2, inclusive, per silicon atom, between 20 and 70 per cent of the total phenyl and methyl radicals being phenyl radicals, an alkali metal is reacted with the chloro-silane CH3.C6H5.SiCl2 or a chloro-silane mixture having the average formula (CH3)n.(C6H5)m.SiCl4-n-m, in which the value of n+m is from 1.2 to 2 inclusive and m/n+m is from 0.2 to 0.7.  The reaction may be effected either by adding the alkali metal, such as sodium, potassium, caesium, rubidium or sodium-potassium eutectic, to the chlorosilane(s) or by adding the chlorosilane(s) to a dispersion of the alkali metal in an aliphatic or aromatic hydrocarbon, e.g. toluene and xylene, and at temperatures preferably between 50 DEG  and 200 DEG  C.  The product may be conventionally purified from residual alkali metal and the alkali salts produced by the reaction.  Chlorosilanes specified are CH3SiCl3, C6H5.SiCl3, C6H5.CH3.SiCl2, (C6H6)2.SiCl2, (CH3)2.SiCl2, (C6H5)3SiCl, (C6H5)2CH3.SiCl, C6H5.(CH3)2SiCl and (CH3)3SiCl.  The thermoplastic products may be used in molten state or in solvents such as petroleum-naphtha, xylene or toluene, for coating surfaces.  The resin thus applied may be thermally set by heating in air or other inert gas such as nitrogen or flue gas.  The resins may also be used for electrical insulation and for thermoplastic moulding compositions. Catalysts may be used to increase rate of setting or to lower the temperature required to effect the setting.  Examples are given.

Title: Improvements in electric and electronic driving circuits for friction presses
IPC: B30B15/14
Filed: 1957-04-01
Abstract: 844,533. Switching systems for mechanically driven presses. WALCHHUETTER, U. April 1, 1957 [July 21, 1956], No. 10574/57. Drawings to Specification. Class 38 (4). A screw-down press is frictionally driven by discs which are displaceable to engage a driving wheel so as to enable the pressing member to be moved either towards or away from the work, the work being extracted from the press by a carriage which moves to and from the press in synchronism with the movement of the pressing member, the arrangement being provided with a system of relays, push buttons and contacts which are operated by the movement of a member attached to the pressing member and an electric motor which drives the press and the carriage through electromagnetic clutches. The system is arranged so that the carriage can advance and retract only when the press is at the point in its travels furthest from the work. Should the mould not reseat itself at the end of the forward travel of the carriage the press will be stopped and in the event of stoppage of the press the carriage will continue its operation until it is fully extracted from the press. The press cycle is arranged to contain two impacts on the work the first of a relatively small force and the second of a considerably greater force. Should the press drop below a predetermined level a limit switch is operated to cause the press to return to its upper position. An electronic circuit arrangement is provided whereby the energization of the clutch through which the press is driven has an initial value which is very high which value is subsequently reduced, this circuit also functioning to maintain the current in the clutch operating winding constant despite variations in the voltage of the supply.

Title: Improvements in the manufacture of buffing units
IPC: A46B3/00
Filed: 1947-04-23
Abstract: 634,512. Grinding and polishing; polishing appliances; brush-making apparatus. ARMSTRONG, J. J. V. (Jackson Buff Corporation). April 23, 1947, No. 10801. [Classes 19 and 60] A method of forming rotary buffs and similar articles comprises winding a strip 59 of material in the form of a cylinder, applying a peripheral contraction to the cylinder intermediate its ends to fold the cylindrical material into a substantially flat form, then applying axial pressure to the folded material and clamping the inner peripheral margin of the folded material while subject to the axial pressure. The material, which may be paper, felt, bias-cut fabric, rows of bristles or wires, or combinations of such materials, is fed from a supply roll 10, Fig. 1, on to two drums 35 and 36. The drum 35 is carried on a member 30 which is rotatably and slidably mounted in a bracket 29 having an L-shaped slot 33 'to receive a stud 32 on the member; the member 30 carries a pivoted operating-handle 31 which is pivotally secured to a fixed bracket 54. The drum 36 is mounted in a bracket 37 carrying a cylinder 41 containing a piston having a rod 42, Fig. 3, formed with a substantially rectangular end 44 to co-operate with a corresponding slot 45 in the member 30. Both drums are driven through chain drives from a motor 46 and are provided with clips 65 to secure the material. The handle 31 enables the member 30 and the drum 35 to be locked on to the piston-rod 42 at a pre-determined axial distance from the drum 36 prior to winding the material. When the required quantity of material has been wound on to the drums and severed from the supply roll, blades 17, Fig. 10, are contracted into the space between the drums, giving the material a substantially flat form. These blades are pivoted at one end to an annulus 15, Fig. 2, and have pins at their other ends engaged by slots in a ring 20 which is mounted on rollers 27, 42 secured to the annulus for effecting contraction of the blades when it is angularly displaced by a pneumatic cylinder 24. This assembly is mounted on a carriage 14 moved into and out of operative position by a pneumatic cylinder 60. A safety-valve incorporated in the pneumatic control system prevents the blades 17 from being contracted before the carriage 14 reaches its operative position. When the material has been completely compressed into the axial space between the drums, a clamp 39, Fig. 3, which is previously placed on a circular series of projections 38, is folded so that teeth 60 on its flanges are pressed into the inner periphery of the material. This is accomplished by admitting air to the cylinder 41 to cause the pistonrod 42 to reduce the axial distance between the two drums. The blades 17 are now withdrawn, and a final clamping pressure applied. Hollow rivets and washers may be substituted for the clamping ring. The finished unit is shown in Fig. 7.

Abstract: 829,980. Making heat-exchangers; brazing. GENERAL MOTORS CORPORATION. April 3, 1958 [April 29, 1957], No. 10817/58. Addition to 827,499. Classes 83 (2) and 83 (4). [Also in Groups VIII and XIII] In making a heat-exchanger an assembly of a sheet of heat-decomposable material and a plurality of parallel wires is formed, the assembly is corrugated transversely of the wires, the unitary structure formed is positioned between a pair of conduits and the whole assembly of conduits and structure is heated to decompose the sheet material and unite the wires to the conduits so that the wires form fins. Parallel wires 22, Fig. 4, are placed on a polyethylene sheet 26 and a second polyethylene sheet 28 is placed thereon and by heat or a bonding agent the sheets are bonded together at 30 and possibly to the wires. Alternatively wires 22, Fig. 5, are passed through a die which extrudes polyethylene 40 on to the wires and forms webs 42. The assembly is corrugated between dies or teeth on gear-wheels, the bases of the wires being flattened. The structures are inserted into and between conduits 16 connecting headers 12, 14 of an air-conditioning evaporator 10, the wires being parallel to the conduit axes. The whole assembly is heated to 1130‹ F. so that the polyethylene decomposes and a coating of brazing alloy on the conduits brazes the wires to the conduits. The alloy may be a coating on the wires or may be in ribbon, wire or powder form between the wires and conduits. Polyvinyl chloride or polyvinyl acetate may replace the polyethylene.

Title: Improvements relating to grinding wheels
IPC: B24D5/06
Filed: 1936-04-16
Abstract: 459,470. Grinding-wheels. NORTON GRINDING WHEEL CO., Ltd., Bridge Road East, Welwyn Garden City. April 16, 1936, No. 10941. Convention date, April 18, 1935. [Class 60] [See also Group II] A grinding-wheel, such as a pulpstone for producing wood pulp, is formed of a number of bonded abrasive segments 10 individually secured to a rotatable central support 30 by anchorage means 21 embedded in and integrally secured to the segments and connected by an elongated tension member 33 to the central support. The segments may be composed of silicon carbide or crystalline alumina with a vitrified ceramic bond such as porcelain or glass. In the form shown in Figs. 1 and 2, nuts 21 are embedded in recesses 22 in the segments by babbitt metal, cement, sulphur or the like, and are connected by bolts 33 under predetermined tension to a central iron mandrel 30. The bolts may be sufficiently elastic to compensate for radial expansion of the segments during grinding, as described in Specification 285,331, [Class 60]. The spans between the segments are filled with compressible material 35, as described in Specifications 285,331 and 333,658, [Class 60], preferably a rubber compound which may be vulcanized in position, and preferably a " hard " rubber containing at least 20 per cent of sulphur and also granular abrasive, a suitable composition comprising smoked sheet rubber, sulphur, and granular silicon carbide in the proportions of 50, 27 and 23 per cent by weight respectively. The assembly of the mandrel and segments is then heated to vulcanize the rubber filling, after which the space between the mandrel and segments is filled with cementitious material, such as concrete, in which reinforcing members may be embodied. The bolts 33 are prevented from adhering to the cement by a coating of oil, paper, &c., so that the elastic properties of the bolts and the filling 35 prevent the transmission of internal strains between the segments. A broken. segment may be individually removed and replaced by a new one, similar but partially vulcanized rubber sheets, or other deformable material such as babbitt metal, being used for the filling 35. In the modification shown in Fig. 3, anchoring devices 54 are partially embedded in recesses 52 in the segments and partly in the central cementitious support 50. The central support is cast in position after the segments, with the anchors embedded in them, have been assembled and the intervening rubber filling has been vulcanized.
Patent GB-417794-A (GB)
Title: Process for the manufacture of carbazole compounds
Filed: 1933-04-12
Abstract: Carbazole - 2.3.6.8 - tetrasulphonic acid is prepared by sulphonating carbazole in the presence of an agent capable of chemically binding the whole of the water liberated in the reaction, such agent being present throughout the entire course of the reaction.  Thus fuming sulphuric acid or phosphorus pentoxide may be present throughout the sulphonation.  In a modified procedure the carbazole is dissolved in fuming sulphuric acid at a temperature below that which sulphonation takes place, and this solution is then mixed with a suitable water-binding agent, such as fuming sulphuric.  By subjecting the tetrasulphonic acid to an alkali melt at temperatures up to 200 DEG C. the 2-sulpho group is replaced by hydroxy; using aqueous caustic alkali temperatures of 225--280 DEG  C. are required.  By subjecting the resulting oxytrisulpho derivative or the original tetrasulphocarbazole to a caustic alkali melt at a temperature above 200 DEG  C., 2,8-dihydroxy-3,6-disulphocarbazole is obtained.  Both hydroxysulphocarbazoles on heating with water in the presence or not of a dilute mineral acid under superatmospheric pressure split off the sulpho groups (cf. Specifications 320,641, [Class 2 (iii)], and 341,905).  In examples: (1) carbazole is sulphonated in the presence of fuming sulphuric acid or phosphorus pentoxide to give a 2,3,6,8-tetrasulpho derivative; (2) the tetrasulpho derivative of (1) is fused with potash at 175--185 DEG  C. or with aqueous soda (30 per cent) at 240--250 DEG  C. in an autoclave to give 2-hydroxy-3-6-8-trisulphocarbazole; (3) carbazole-2,3,6,8-tetrasulphonate is fused with potash at 230--240 DEG  C. to give 2.8-dioxy-3,6-disulphocarbazole which is converted to 2,8-dioxycarbazole by heating under pressure with aqueous dilute mineral acid.  The prior art in a few German Specifications is referred to.
